E.2.1 | Main objective of the trial |
To assess the effects of sevoflurane on intra-and postoperative patients undergoing myocardial revascularization surgery compared to propofol in terms of harm reduction and myocardial injury |
Evaluar los efectos de la administración de sevoflurano en el intra y postoperatorio de los pacientes intervenidos de cirugía de revascularización miocárdica respecto al propofol en cuanto a disminución del daño y lesión miocárdica |
|
E.2.2 | Secondary objectives of the trial |
Knowledge of the mechanisms by which myocardial protection occurs in both intraoperatively and postoperatively, determining which of the different effector pathways of preconditioning and postconditioning
Determine length of stay in the intensive care unit of each of the groups to determine if the potentiation of the effect through the postoperative administration, reduces per se the stay in the intensive care unit
Identify differences in rhythm disorder episodes (tachyarrhythmias), thanks mainly to the effects of postconditioning, and the biochemical basis of this beneficial effect |
Conocimiento de los mecanismos por los cuales se produce la protección miocárdica, tanto en el intraoperatorio como en el postoperatorio, determinando cual de las distintas rutas efectoras del precondicionamiento y postcondicionamiento
Determinar días de estancia en la unidad de cuidados intensivos de cada uno de los grupos, para conocer si la potenciación del efecto a través de la administración en el postoperatorio inmediato, disminuye per se la estancia en la unidad de cuidados intensivos
Identificar diferencias en episodios de trastorno de ritmo (taquiarritmias), gracias principalmente a los efectos del postcondicionamiento, y las bases bioquímicas de este efecto beneficioso |
